(1) Safety Instructions
Please be familiar with all information in this quick installation guide and product manual
prior to installation and operation.
Note 1: The products described contain a Class 1 laser or LED fiber optic emitter. The following
safety precautions apply.
Warning: Do not disconnect the fiber optic connector while the unit is powered up.
Exposure to Class I invisible optical radiation is possible when the internal fiber optic
connector is disconnected while the unit is powered up.
Caution: Any access to the controls, adjustments, or performing operations, which are
other than those specified may result in hazardous radiation exposure. Permanent eye
damage or other bodily injuries may be resulted from such exposure even for only
seconds.
Note 2: This assembly contains parts sensitive to damage by electrostatic discharge (ESD). ESD
precautionary procedures should be applied in the course of touching, removing or inserting parts
or assemblies.

(2) Installation
2.1 General
All OT Systems products are thoroughly inspected, tested and securely packaged before
delivery to ensure a stable, intact and trouble-free service. Please check the equipment upon
receipt for any visible damage which may have been caused during shipping.
The NHD110DRMicro units can be either horizontally or vertically wall-mounted, or mounted
on any fixture, etc. The Micro unit works with an external power supply 12VDC powered by local
110/220V power.
2.2 Micro unit installation
a) Mount the clip onto a fixture, e.g. a plank, (either on the wall or on a flat surface) with two
screws piercing through the holes on the mounting frame to secure it in position.
b) The power supply should also be mounted on the same fixture or in the proximity for
connection of the supply cables to the unit, provided that an AC power supply socket is near by
for powering the adaptor.
c) Push the Micro unit into the clip to secure it in position.
d) Connect all the signal inputs and outputs of the unit with appropriate cables:
i) fiber optic cable for optical link,
ii) BNC cable for SD-SDI or HD-SDI input/output (Tx/Rx).
iii) UTP cable for data input/output (Tx/Rx).
e) Once the unit is powered up, check that the red PWR LED on the unit is lit. If not, check the
power supply cable connections between the unit and the power supply socket.
f) With all the signals available at the input and output ports, check the status of LEDs located
on the unit. With correct status of each LED, installation is now completed [for LEDs status, see
Operational Guides on this manual’s section (4)].

3.2 Dip switch setting procedures
The only setup procedure is to select the appropriate line terminations and data
transmission formats. Selections must be made by setting the dip switches through the access on
the front panel.

(4) Ground connections
For enhanced safety to reduce the risks of electrical shock and physical damage, caused by
lightning and other power surges, as well as a connection to the surge suppresion devices in the
product, a screw terminal is provided on the Micro cabinets. It is highly recommended that the
Micro unit have good ground connections to the buildings ground in accordance with the local
codes.
